Answer 2

Calculation of the Percentage of the Book Read by Each Girl

To calculate the percentage of the book read by each girl, we need to divide the number of pages read by each girl by the total number of pages in their respective books and then multiply by 100.

Let's calculate the percentage of the book read by Masha first:

Masha read 235 pages out of a total of 454 pages in her book.

To calculate the percentage, we can use the following formula:

Percentage = (Number of pages read / Total number of pages) * 100

Substituting the values, we get:

Percentage of Masha's book read = (235 / 454) * 100

Now, let's calculate the percentage of the book read by Natasha:

Natasha read 197 pages out of a total of 365 pages in her book.

Using the same formula as above, we get:

Percentage of Natasha's book read = (197 / 365) * 100

Now we can calculate the percentages:

Percentage of Masha's book read = (235 / 454) * 100 = 51.76%

Percentage of Natasha's book read = (197 / 365) * 100 = 53.97%

Therefore, Masha has read approximately 51.76% of her book, and Natasha has read approximately 53.97% of her book.
